A New Generation Framework for Petroleum Reservoir Simulation
As part of the ACTI project, we have developed a simulator framework IPARS (Integrated Parallel Accurate Reservoir Simulator) to serve as a test-bed for multiphase flow models, numerical discretizations, solvers, and upscaling.
Portability between different platforms including PC under DOS/Windows or Linux and PC clusters, RS6K and SP2, SGI, Cray T3E, etc.
Memory management for multiple fault blocks, multiblock nonmatching grids and general geometry.
Multiple processors (ghost region updates and global reduce operations)
Time step control
Error management, CPU timing system
Visualization output for scalar and vector variables, data tables etc.
A suite of linear solvers
Well management tools for different types of injection and production wells
Multiple physical models including
Two phase (oil/water) implicit,
Two phase (oil/water) sequential (Fast Accurate),
Black oil (three phase, three component),
Two phase (air/water) implicit,
Single phase (slightly compressible) explicit,
Single phase (slightly compressible) implicit,
EOS compositional (in review phase, also see EOS page),
And much more (some still in development phase)…
Multiblock formulation using mortar spaces and implemented with MACE
Multimodel formulation allowing for multinumerics and multiphysics
